Abstract

Hydroxycitric acid (HCA) a bioactive compound found In Garcinia species, is a potent initibitor of fatty acid and cholesterol synthesis. Studies have shown that HCA decreases weight by inhibiting lipogenesis; the metabolic process that changes carbohydrate into fat and also lowers blood lipid levels. Since it reduces both lipid synthesis and appetite, HCA Is believed so be a potentially useful agent for producing a weight controlling herbal product in the future. HCA could be extracted using water extraction process although the extraction parameters such as temperature, duration and solid-to-water ratio were found to have a significant Influence on the yield and HCA content. Therefore, optimization of the extraction process was carried out to develop a generalized approach for aqueous extract preparation or Garcinia atroviridis (asam gelugor) with optimal extraction yield and HCA content. Results revealed that the best extraction parameters to obtain the highest yield and HCA concentration from G. atroviridis were temperature of 100⁰C, solid-to-water ratio at 1:10 and duration for 6 h. The highest extraction yield and HCA concentration were 51% and 589.64 µg/mI, respectively.
